Lim ZW, Chee ML, Lim SH, et al. - Researchers conducted this multiethnic population-based study to assess the normative profiles for neuroretinal rim area (RA) in a multiethnic Asian population. Participants were selected from the Singapore Epidemiology of Eye Diseases (2009–2015) study and underwent standardised examinations. Multivariable linear regression with generalised estimating equation model was used to assess the connections between demographic, systemic and ocular factors with RA. In total, 9,394 eyes from 5,116 individuals (1,724 Chinese, 1,463 Malay, 1,929 Indian) were involved in the final analysis. Compared with Chinese and Malays, the authors found significantly smaller RA in Indian eyes. This suggests the need for Asians to provide more refined ethnic-specific RA normative databases.
